C20530A-453

Overview

The C20530A-453 is a two-line common mode choke manufactured by ITG Electronics, Inc., designed for through-hole mounting. It features an inductance of 45 mH measured at 10 kHz and supports a maximum current rating of 3.6 A. The component exhibits a DC resistance (DCR) of 85 mOhm. This toroidal inductor is part of the C20530A series, which utilizes alloy powder cores to achieve lower core loss and distributed capacitance. The device operates within a temperature range of -55°C to +130°C and complies with RoHS and HF standards.

Feature Summary

• Utilizes alloy powder based construction for reduced core loss and low distributed capacitance
• Features coil mount on UL94-V0 rated plastic header with fixed pin spacing for easy PCB insertion
• Designed as a compact single wire wound toroidal inductor suitable for switch mode power supplies

Applications

• Switch mode power supply filtering
• Common mode noise suppression in electronic circuits
• EMI filtering applications requiring through-hole mounting

Procurement Notes

Verify the specific inductance tolerance and current ratings against the official ITG Electronics datasheet before integration. Confirm that the through-hole package dimensions match the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when a high-inductance common mode choke with moderate current handling is required for through-hole designs. The 45 mH value at 10 kHz makes it suitable for specific frequency filtering needs. Consider the 3.6 A current rating and 85 mOhm DCR for power loss calculations. The alloy powder core offers advantages in efficiency compared to standard ferrite cores in certain high-power applications.
